How can I find out on my Fedora 25 what port I have to open up for a program to work? I recently purchased a Multifunction Canon Printer TS5000 series. They use a propetary program for scanning images called ScangearMP . When I execute scangearmp2 it cannot find the printer on the wireless network. If I drop the firewall, then scangearmp2 indeed finds the printer. How can I find out what firewall ports scangear is trying to use? I tried netstat but the listing I saw was kind of large and did not immediately make sense to me.printer: ipp protocol port 631 You have a list of ports and associated devices/protocols in /etc/serveces know what if any ports are in use for anything, but I figured I might find out. --doug
